The development of advanced materials with pre-selected properties is one of the main goals of materials research. Of special interest are electronics, high-temperature and superhard materials for various applications, as well as alloys with improved wear, corrosion and mechanical resistance properties. The technical challenge connected with the production of these materials is not only associated with the development of new specialized preparation techniques but also with quality control. The energetic charged particle, electron and photon beams offer the possibility of modifying the properties of the near-surface regions of materials without seriously affecting their bulk, and provide analytical tools for testing their quality. This text provides an overview of this rapidly expanding field. Fundamental aspects concerning the interactions and collisions on atomic, nuclear and solid state scale are presented in a didactic way, along with the application of a variety of techniques for the solution of problems ranging from the development of electronics materials to corrosion research and from archaeometry to environmental protection.It is divided into six thematic units: fundamentals, surface analysis techniques, laser beams in materials technology, accelerator-based techniques in materials technology, materials modification and synchrotron radiation.

The natural microporous materials include several types of minerals such as zeolites, clay minerals, micas, Fe-lMn- oxides/hydroxidesloxyhydroxides present in various geo- logical environments and soil formations. Their crystal structure is characterised by the presence of intra crystal micropores (channels or interlayer void spaces) providing high microporosity/surface area and distinguished physico-chemical properties such as cata- lytic and sorptivelion-exchange ones. This volume includes the key- lectures and participant contributions delivered at the NATO-funded Advanced Research Workshop on the Application of Natural Microporous Materials for Environmental Technology, which was held in the th Smolenice Castle, Slovakia, from the 2()1h to 30 of October 1998 and was attended by 55 participants from 17 countries.The purpose of the workshop was the critical assessment of the current developments and discussion of the future perspectives in the field of utilisation of natural microporous materials (zeolites, clays, oxides) for the solution of problems related to the toxic and nuclear waste management, water pollution control and decontamination, the environmental catalysis associated with atmospheric pollution, the creation of new materials for energy storage and agricultural management including the development of artificial soils for plant growth in the space. Of especial importance for this meeting was the exchange of information and know-how among specialists working in institutions of NATO and Cooperation Partner countries aiming towards the development of common strategies for the solution of environmental problems and the promotion of further scientific and technological collaboration in the field.
